PURPOSE:To obtain a molding, using a simple apparatus with simple operation, that has a colored resin layer that is favorably retained, by laminating a colored resin layer, a transparent resin layer stable at high temperatures, and a transparent resin layer capable of shielding ultraviolet ray. CONSTITUTION:A colored resin layer 2, a transparent resin layer 3 stable at high temperatures and a transparent resin layer 7 capable of shielding ultraviolet ray are laminated by welding or by an adhesive to be formed into a sheetlike material 1. The sheetlike material 1 is fed to an extrusion mold and is extruded and molded to weld, at the vicinity of the mouth piece outlet, the colored resin layer 2 to the surface section of the molding main body 4 and to form a colored resin layer 5. At this time, although the colored resin layer 2 is softened at a temperature of the resin forming the molding main body 4 and is welded to the main body 4, since the transparent resin layer 3 keeps the sheetlike state without softening, the colored resin layer 2 will not become out of order thereby forming the colored layer 5 that has a uniform appearance and is retained securely. |
